I don't know anything about stratovan. In Slicer, you can simply choose not to compress the PLY during the saving and it will output an ASCII PLY. Given that is starts with a text header, and goes binary makes me wonder if they are doing a similar thing. Perhaps they have an option not to compress the files?
